6. Of the Incarnation of Christ Jesus
When the fullness of time came a, God sent His Son, His eternal wisdom, the substance of His own glory, into this world, who took the nature of manhood of the substance of a woman, to wit, of a virgin, and that by operation of the Holy Ghost b, and so was born the just seed of David, the angel of the great counsel of God, the very Messiah promised c. Whom we acknowledge and confess, Immanuel, very God and very man, two perfect natures united and joined in one person. By which our confession, we condemn the damnable and pestilent heresies of Arius, Marcion, Eutyches, Nestorius, and such others, as either deny the eternity of His Godhead, or the verity of His human nature, or confounded them, or yet denied them.
